The BS* + Beer Show: The Science of Concrete

This episode of the BS* + Beer show features Trevor Acorn, Helen Watts, and Christopher Genest discussing the science of concrete. Trevor gives a brief history of the material and an introduction to its chemical makeup. He talks about concrete mix proportioning, the importance of durability over strength, and the holy grail of low permeability. Helen gets into a bit on testing, reinforcement specifics, and persistent problems she has seen over the years. Chris introduces us to his company’s Comfort Block, explaining its properties and evolution, which was influenced by German products. Together they give a well-rounded overview of this highly complex subject. 

Enjoy the show!

Join us on Thursday, May 20, from 6 to 7:30 p.m. EST when Doug Horgan, Bob Kovacs, and Rick Thomas will take a look at some of the ways the commercial construction industry might influence the residential building sector. As Mike Maines puts it: “To the casual observer, commercial construction projects probably look a lot like residential construction projects: big equipment, lots of dust, noise, and tradespeople—and eventually a building emerges. But commercial construction projects are often much larger and more complicated than residential projects, with different priorities and stakeholders involved. What lessons can residential designers, builders, and clients learn from commercial construction? What can commercial construction teams learn from the residential world?” These are a few of the many questions our guests intend to address.
